EPA is proposing significant new use rules (SNURs) under TSCA for certain chemical substances that were subject to premanufacture notices (PMNs) and TSCA Orders. Once finalized, these SNURs would require 90-day advance notification to EPA before manufacturing or processing these substances for designated significant new uses. This allows EPA to evaluate conditions of use before activities commence. Companies handling PMN substances should review the proposed designations.
EPA announced the availability of the draft risk evaluation for 1,1,2-trichloroethane under TSCA and is seeking public comment. This solvent is used in chemical manufacturing and as an intermediate. The draft risk evaluation determines whether the chemical presents unreasonable risk to health or the environment under conditions of use. Comments inform EPA's final determination and any subsequent risk management actions.
EPA finalized extensions to compliance dates for perchloroethylene (PCE) and carbon tetrachloride (CTC) risk management rules under TSCA. Initial monitoring compliance extended to June 21, 2027. ECEL compliance, regulated areas, training programs, and PPE requirements extended to September 20, 2027. PCE exposure control plan deadline extended to December 20, 2027. This affects manufacturers, processors, and users of these solvents who must implement Workplace Chemical Protection Program requirements.
EPA has issued a final Significant New Use Rule (SNUR) under TSCA for multi-walled carbon nanotubes, a chemical substance subject to a premanufacture notice (PMN) and EPA Order. The SNUR requires 90-day advance notification to EPA before manufacturing or processing the substance for designated significant new uses. This enables EPA to evaluate conditions of use before the activity commences.

Once finalized, the SNURs would require 90-day advance notification to EPA before manufacturing or processing these substances for designated significant new uses. This proposal initiates a public comment period.
EPA is seeking public input to develop a durable TSCA regulation for legacy uses and associated disposals of asbestos (Part 2 risk management rule). TSCA section 6(c)(1)(C) authorizes EPA to adjust the proposed rule deadline when additional information is necessary. EPA finalized the asbestos Part 2 risk evaluation in December 2024. The agency requests information on activities that disturb asbestos-containing materials, use of legacy products, and air-sampling methods.
EPA is advancing its TSCA review of five chemicals by releasing draft technical support documents for peer review and public comment. The chemicals are: 1,1,2-trichloroethane, TBBPA (tetrabromobisphenol A), 1,2-dichloropropane, and two additional chemicals. These documents support ongoing risk evaluations under TSCA Section 6. Manufacturers, processors, and other stakeholders should review and provide input during the peer review and comment period.
EPA published a notice of availability and request for comment on the TBBPA (4,4′-(1-Methylethylidene)bis[2,6-dibromophenol], CASRN 1163-19-5) risk evaluation under TSCA Section 6. TBBPA is a brominated flame retardant used in electronics, plastics, and other applications. The comment period ends August 17, 2026. Stakeholders should submit comments on the draft risk evaluation to inform EPA's final determination.
The EPA has proposed Significant New Use Rules (SNURs) under TSCA Section 5 for chemical substances that were the subject of premanufacture notices (PMNs) and TSCA Orders. The SNURs would require persons intending to manufacture or process these chemical substances for activities designated as significant new uses to notify EPA at least 90 days before commencing that activity. This is Batch 26-1 of proposed SNURs.
EPA announced it will move forward with TSCA section 6(a) risk management to regulate 15 industrial and commercial conditions of use of 1,2-dichloroethane (1,2‑DCA), based on EPA’s final risk evaluation finding unreasonable risk to workers in 15 of 20 conditions of use (driven by inhalation and dermal exposure). EPA stated it did not identify unreasonable risk to consumers, the general population (including fish-consuming/Tribal communities), or the environment under evaluated conditions of use. Compliance teams should anticipate forthcoming workplace-focused restrictions/controls for affected 1,2‑DCA uses and monitor the referenced docket activity for proposed requirements, timelines, and any exemptions.
EPA published a rolling public list of TSCA Confidential Business Information (CBI) claims scheduled to expire (including claims expiring between June 22, 2026 and July 31, 2026) and stated it will refresh the list monthly. EPA also described a new electronic extension-request process in EPA’s Central Data Exchange (CDX) using a dedicated tool (TSCA Section 14(e) CBI Claim Extension Request). Companies must submit extension requests with substantiation no later than 30 days before claim expiration to maintain confidentiality protections; otherwise, EPA may no longer be required to protect the information from disclosure. Compliance teams should inventory TSCA submissions with CBI claims, monitor the monthly expiring-claims list, and prepare CDX extension filings within EPA’s stated timing window.
EPA announced important policy updates to the TSCA New Chemicals Program. Key changes include: EPA will no longer issue 'not likely to present unreasonable risk' determinations based on proposed SNURs; worker protections will be mandated through TSCA Section 5(e) orders rather than relying on OSHA standards; and EPA will identify absence of worker safeguards as 'reasonably foreseen' conditions of use. EPA remains committed to meeting statutory deadlines for review and determinations on new chemicals submissions.
EPA announced a final rule on May 22, 2026 extending the TSCA Section 8(d) Health and Safety Data reporting deadline to May 21, 2027 for all 16 chemicals covered under the rule. Manufacturers (including importers) of these 16 chemicals must report data from unpublished health and safety studies to EPA by the new deadline.
EPA announced a proposed rulemaking to extend certain compliance dates in the final TSCA §6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC). EPA stated existing compliance dates remain in effect unless and until revised through rulemaking, but EPA intends to focus compliance/enforcement resources on the new compliance dates that would be established if the proposal is finalized. Compliance teams using or supplying PCE/CTC should track the proposal and be prepared to re-baseline internal Workplace Chemical Protection Program timelines and related operational controls once new dates are finalized.
EPA published draft TSCA risk evaluation materials: draft risk evaluations for HHCB and phthalic anhydride and draft hazard assessments/supporting documents for o-dichlorobenzene and p-dichlorobenzene. EPA also announced Science Advisory Committee on Chemicals (SACC) peer review meetings (including a preparatory meeting) as part of the TSCA risk evaluation process. Compliance teams should review the drafts, consider submitting comments to the peer review docket, and assess whether conditions of use identified as presenting unreasonable risk could lead to future TSCA §6 risk management requirements if finalized.
EPA extended the public comment period for the proposed TSCA Section 5 Significant New Use Rules (SNURs) titled “Significant New Use Rules on Certain Chemical Substances (26-2).” The comment deadline is extended to July 10, 2026. This affects stakeholders planning to submit comments on the proposed SNURs and provides additional time to evaluate potential impacts on manufacturing (including import) or processing of substances subject to TSCA orders and SNUR-based notice requirements (SNUNs) prior to designated significant new uses.
EPA issued notice of the final risk evaluation for 1,2-dichloroethane under TSCA. This completes the risk evaluation process for this chemical substance, determining whether it presents unreasonable risk of injury to health or the environment under its conditions of use. The final risk evaluation informs potential risk management actions under TSCA Section 6.
EPA proposed Significant New Use Rules (SNURs) for chemical substances subject to premanufacture notices (PMNs) P-25-73, P-25-152, P-25-137, and P-25-151. The SNURs require 90-day notification (SNUN) to EPA before manufacturing or processing for significant new uses. EPA identified concerns for carcinogenicity, reproductive toxicity, specific target organ toxicity, and dermal/respiratory sensitization. Estimated cost per SNUN submission is $45,496.
EPA issued a proposed rule to add Significant New Use Rules (SNURs) for certain chemical substances subject to TSCA consent orders. The proposal would require companies to submit a Significant New Use Notice (SNUN) at least 90 days before manufacturing or processing for a designated significant new use. Compliance teams should identify whether any affected substances are in their portfolios and consider commenting by the deadline; if finalized, SNUN planning/lead times and use restrictions may affect R&D, scale-up, importing, and downstream customer applications.
EPA published a proposed rule to establish Significant New Use Rules (SNURs) for certain chemical substances (SNUR batch 26-2). If finalized, manufacturers and processors would be required to submit a Significant New Use Notice (SNUN) at least 90 days before commencing any activity designated as a significant new use (generally, activities not consistent with protective measures in underlying TSCA §5 orders). Compliance teams should determine whether any portfolio substances or planned uses could be affected and consider submitting comments by the stated deadline.
